Catechol-O-Methyltransferase Polymorphism and Endometriosis
This case-control study investigated whether a COMT gene polymorphism associated with low enzyme activity is linked to endometriosis risk in women.

This case-control study evaluated whether a COMT exon 4 valine-to-methionine polymorphism (low-activity allele COMT-L) is associated with endometriosis by genotyping women with surgically and histologically confirmed endometriosis (n=91) and women without evidence of endometriosis confirmed by laparoscopy or laparotomy (n=92). Allele frequencies for COMT-L were identical in cases and controls (0.50 vs 0.50; p=0.999; odds ratio 1.0, 95% CI 0.66–1.51), indicating no association between this COMT polymorphism and endometriosis risk. A key limitation is that the study tests a single genetic variant as a proxy for COMT activity and does not report broader genetic, biochemical, or functional measures of catechol-estradiol metabolism beyond genotype. This paper is centrally about endometriosis — it directly tests COMT polymorphism association with surgically confirmed disease.
